Got a situation with a MF 65. On the upswing with a complete rebuild getting to the axle tubes and the brakes. Soon after getting the axle tube with brake assembly inside bolted up to the rear end we noticed that the disks are tight. This has the nasty impact of not allowing the disks to move and accommodate the half shaft insertion. When we first loaded the brake actuator we noticed it was fairly tight fitting into the casting. The tightness didn't offer much resistance and just seemed like something you might encounter with new parts. The actuators appear to be more or less symmetrical in design aside from the lever attachment points. We checked both orientations and both seemed to fit the same. Both actuators and both axle tubes fit the same. I noticed after we installed the tube I could see a hint of the ball bearings which tells me the actuators are open by about 1/16" of an inch. I didn't notice this prior to install so I don't know if this the "start" position or if they are opened up. What do I do? If I didn't know any better I would say I needed to mill metal off the new actuators but that makes no sense on new parts. Anybody have insight about this problem?
